SPECIFICATION forming part of Letters Patent No. 410,135, dated August 2*?, 1889.

Application led. November 17, 1888. Serial No.291,085. (No model.

To all whom, t vita/y concern:

Be it known that we, CHARLES O. BRUCK- NER and HENRY WV. THORNTON, citizens of the United States, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Optical Apparatus, of which the following is a specification.

Our invention is a new apparatus for auto- 1n atically exhibiting upon a screen or the like a series of illuminated pictorial or other objects in succession for advertising or other purposes; and it consists of a certain novel combination of lenses and reiiectors with an intermittingly-revol ving plate-carrier for `receiving a series of glass plates with the desired objects thereon, and amotor for operating the plate-carrier, as hereinafter more fully described, and illustrated inthe accompanying drawings, in which- Figure 1 represents a rear elevation, partly in section. Fig. 2 represents a vertical section thereof on the line x fr, Fig. l. Fig. 3 represents a horizontal section thereof on the line y y, Fig. 1. Fig. 4 represents a like section thereof 011 line .e z, Fig. 1. represents a cross-section of a lens-holder detached.

Similar letters of reference indicate corre-` the arm engages either stop-pin the latter is sponding parts.

The letter A indicates two vertical rods rising from a base or platform B, and support-l ing two cross-heads O O', one above the other.

disk, in which is formed a circular row or se-4 ries of light-orifices G', each corresponding to said light-orices D D of the cross-heads, and which is mounted on a vertical shaft or spindle I, having its bearings in said frame in such a position relatively to the light-orifices of the cross-heads that the circular lens intersecting the axis of the carrier-orifices also intersects the axis of the head-orifices,

Fig. 5

and hence by revolving the plate-carrier each of its orifices may be brought directly opposite to the head-orifices. Each of said lightorifices G' of the plate-carrier is in practice fitted with a glass plate, as at G2, Fig. 3, on which plate' the selected object to be exhibited is properly inscribed, and which is held fast, as by edge-gages, on the proper face of t-he carrier. Immediately above the` platecarrier 'G is located a tappet-arlnJ, which is mounted on a vertical shaft J', having its bearings on the frames O C in such a position relatively to a circular row or series of stop pins or teeth Zon the face of the platecarrier that by continuously 4revolving said arm in a horizontal plane it engages with said carrier stop-pins one after another, and by displacing the same imparts to the plate-carrier G intermittin gly a degree of.1notion equal to the distance between the carrier light-ori- `iices G, thereby adjusting the latter in succession to the light-orifices D D of the crossheads. In the lower surface of the tappetarln, and at or near its free end, is formed a transverse groove s, which is preferably t curved, and the inner edge of which is continuous with one edge of said arin where it engages the stop-pins lof the plate-carrier, as shown by dotted lines in Fig. 3, so that when received in said groove, and, traveling through it, is released at a fixed point with a corresponding adjustment of the plate carrier. Said shaft J of the tappet-arm is geared with a motor K, to receive a continuously-revolving motion therefrom for automatically operating the plate-carrier Gr, said motor being in' this example driven by a spring K and the motor-frame properly secured to the lower IOO cated an object-reflector O, which is at anangle corresponding to the angle of the lightreector F2, but usually in a plane opposite thereto, as shown. Said object-reflector O is supported on the vertical rods A, as by means of socket-pieces O, having set-screws O2, for permitting said refiector to be adjusted to dierent heights, and, if desirable, provision may be made for setting the reiiector to different angles.

Opposite to the auxiliary condensing-lens F is located an illuminator P, of any usual or suitable construction, for directing an artificial light upon the reflector F2 through said auxiliary lens, whence such light is thrown upward through the main condensing-lens F upon the glass" plate of the plate-carrier G,

that maybe in alignment, and thence through the magnifying-lens E upon the object-rellector O, and thence upon a screen or the 1 te. Then the apparatus is applied to use, a glass plate with the object to be exhibited-l say a photograph ora print thereon-is placed opposite to each of the light-orifices G on the plate-carrier,a1nl said carrier is put in operation by means of the motor, whereupon the objects represented on the glass plates are successively directed upon the obj ect-reector P at regular intervals of time, under a very strong light, due to the action of the condensing-lens F, and in a magnified form, due to the action of the magnifying-lens E, from which reflector the object may be readily thrown uponfthe desired surface, as of a screen placed opposite thereto, with a highly artistic effect.

In some cases the len ses E F and plate-holder G may be elongated for throwing the object in a direction horizontally instead of verti-4 cally, as in the present example of our invention.

. If deemed desirable, the apparatus maybe arranged to throw objects on the sidewallnor a series of them may be placed in a wagon and the canvas of the wagon used as a screen, thereby affording' a very superior portable advertising medium.

It may be remarked that the vertical rods A may have suitable hangers attached thereto for exhibiting articles of merchandise.

What we claim as new, and desire to secure by Letters Patent, is-

l. An optical apparatus in which are coinbined a magnifying-lens and a condensinglens axially coincident with each other, an intermittingly-revolving plate-carrier having a circular row of light-orifices adapted to ially coincide with said lenses, and a motor for operating said carrier, substantially as and for the purpose described.

2. An optical apparatus in which are combined a magnifying-lens, two condensinglenses at right angles to each other, one condensing-lens bein g axially coincident with the magnifying-lens, a light-reiiector at an angle vto both condensing-lenses, an intermittinglyrevolving plate-carrier havinga circular row o f light-orifices, and a motor for operating said carrier, substantially as and for the purpose described.

3. An optical apparatus in which are combined a magnifying-lens and condensing-lens axially coincident to each other, an object-reflector opposite to said magnifying-lens, an intermittin gly-revolvin g plate-carrier having a circular row of holes between said lenses, and a motor for operating said carrier, substantially as and for the purpose described.

'4. An optical apparatus in which are combined a magnifying-lens, two condensinglenses at right angles with each other, one condensing-lens being axially coincident to said magnifying-lenses, an illuininator opposite to the other condensing-lens, a light-refiector at an angle to both condensing-lenses, an object-reiiector opposite to said magnifying-lens, an intermittingly-revolving platecarrier having a circular row of light-orifices, and a motor for operating said carrier, substantially as and for the purpose described.

5. An optical apparatus in which are combined an intermittingly-revolving plate-carrier having a circular row of light-orifices and a corresponding row of stop-pins, a revolving tappet-arm adapted to engage with said pins of the carrier, a shaft carryingsaid arm, and a motor geared with said shaft, substantially as and for the purpose described.

6. An optical apparatus in which are combined an intermittingly-revolving plate-carrier having a circular rowof light-orifices and a corresponding row of stop-pins, a tappetarin having a transverse groove, the inner edge of which forms a continuation of one edge of said arm for engaging said pins of the carrier, a shaft. carrying said arm, and a motor geared with said shaft, substantially as and for the purpose described.

7. An optical apparatus in which are combined two cross-heads having light-orifices axially coincident with each other, a magnifying-lens fitted in said orifice of the upper cross-head, a condensing-lens arranged below said orifice of the lower cross-head, an intermittin gl y-re volvin g plate-carri er having a circular row of light-orifices, and a motor for imparting motion to said carrier, substantially as and for the purpose described.
